PROCESS OF MANUFACTURING COLORED OR SIMILAR FILMS.

SPECIFICATION forming part of Letters Patent No. 665,458, dated January8, 1901.

Original application filed December 20, 1899, Serial No. 741,058.Divided and this application filed Se t b r 27,1900. Serial No. 31,289.(No specimens.)

To all whom it may concern:

Be it known that I, EnNs'r OESER, manufacturer, a subject of the King ofPrussia, German Emperor, and a resident of Dresdenerstrasse 7 9, Berlin,Germai'iy, have invented a certain new and useful Process ofManufacturing Colored or Similar Films, of which the following is aspecification.

The invention treats of a process for the manufacture of colored andsimilar films the surface of which is figured. Forthis purpose I make amixture of a number of fluid colors, according to the number of thecolors out of which the pattern of the films is to consist, Each coloris mixed as follows: I take, for instance, one-fourth to one-half literof water, dissolve some isinglass in it, add some glycerin, mix in it acorresponding quantity of the coloring-matter in question, and add tothis mixture, kept lukewarm, some albumen. \Vith the preparationobtained by the process just described I then apply the desiredpattern-for instance, stone color or wood colorto a glass plate oranother smooth plane and let the color become dry. Then I pass over thewhole with that color-which is to be the ground color of the film. Thisground color is, however, prepared in the same way as the colors of thepattern. As soon as all has become.dry I scrape the color off from theglass plate by means of a suitable knife, and thus obtain the film. Imay also proceed in a reversed way. I apply (in the manner justdescribed) at first the ground color to the glass plate, and as soon asit has become a little dry I scrape out the pattern and then pass overit with that color by which the pattern is to be figured. After thecoating has become dry I scrape it likewise off from the glass, and thusobtain the film.

To the preparation of each color I choose the following proportions:water, one-fourth to one-half liter; isinglass, five to ten grams;glycerin, ten to fifteen grams; albumen, about thirty grams. Addcoloring-matter until the mixture is suitable to be struck.

In the place of the coloring-matters may be taken bronze powder.

This application is a division of the application filed by me December20, 1899, patented October 16, 1900, No. 660,024.

What I claim, and desire to secure by Letters Patent, is

1. The process of manufacturing figured colored films consisting inapplying to a smooth surface the pattern by means of a color preparedfrom water, isinglass, glycerin, coloring-matter and albumen and byapplying to this, when dry, another coating consisting of water,isinglass, glycerin and other coloring-matter and some albumen, all thisbeing scraped ofi when dry.

2. The process of manufacturing figured colored films, consisting inapplying to a.

smooth surface the pattern by means of colors prepared from one-fourthto, one-half liter of Water, five to ten grams isinglass, ten to fifteengrams glycerin, four hundred to five hundred grams coloringmatter andabout thirty grams albumen, and by applying to it, when dry, anothercoating consisting of onefourth to one-half liter of water, five to tengrams isinglass, ten to fifteen grams glycerin, four hundred to fivehundred grams of coloringmatter and thirty grams of albumen, which isscraped 0E, when dry.

3. The process of manufacturing figured colored films consisting inapplying to a smooth surface a color prepared from onefourth to one-halfliter of Water, five to ten gramsisinglass, ten to fifteen gramsglycerin, four hundred to five hundred grams coloringmatter and aboutthirty grams albumen, in scraping, out of the coating when dry, thepattern, in passing over the whole with another color, prepared fromone-fourth to one-half liter of water, five to ten grams isinglass, tento fifteen grams glycerin, four hundred to five hundred grains ofanother coloring-matter and about thirty grams albumen and in scrapingoi the whole when dry.

4. As a new article of manufacture, a figured film consisting ofisinglass, glycerin, albumen and a color.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
